Furthermore, this invention With reference to the drawings,I have provides a roller bearing so constructed that h wn a rollerbearing comprising rigid oneeach roller forms a tie, eliminating the usep e 8 1d ri gs 1. ach end ring has the urn Previous experience in theroller bearing mortice or groove 3 which is not undercut. art has shownthat the greatest imperfectio It will be noticed that the mortices orgrooves in roller bearings, especially where the roll- '2 are allundercut on thesame side of the ers take end thrusts and are very long,reg ve, 0 in the Sa e direction, the purpose to become disaligned orskewed.

The roller Figure 1 is an endview of my roller replaced inthe groove 3 acts as a key roller tainingmeans with the rollers disposed thereholding the other rollers in suchposition that 109 they cannot slip out of the undercut mortices orgrooves 2.

This hearing, as shown, does not require tie pins or spacing rollers tohold the bearing together as a unit. Each roller has the shoulders 6 and7 formed by the circumferential slots 5 in the ends of the rollers 4.The cage or end ring fitting between these rollers provides a rigid unitwhich cannot twist out of alignment. If the rollers were to be twistedout of line, the shoulder 6 on one side of the end ring would forceagainst the end ring in one direction while the shoulder 7 on theopposite side of the end ring would force against the ring in theopposite direction, tending to bring the roller back; into its properalignment. It will be clearly understood that many minor changes may bemade in the parts or construction of this roller bearing withoutdeparting from the spirit of my invention.

By reference to the preceding description and the drawings attachedhereto, it will be seen that I have provided a roller bearing whereinthe rollers maintain themselves in correct alignment and wherein therollers take the radial strain of the bearing and, also, the lateralstrain or end thrust of both bearing n'lembers.

It will also be clearly understood that I have provided a roller bearinghaving a 11121X- imum rolling surface for the moving parts contactingtherewith and, at the same time, have provided a roller hearing whichmay be readily taken apart or assembled. Likewise, it will be apparentthat the end members may be of cast metal or may be of other material orform and that I am not, necessarily, limited to the use of only twosupporting mem bers for the rollers.

Having thus described my invention, what I claim is:

1. In a roller bearing, the combination of bearing rollers havingperipheral grooves near their ends, an end ring for said rollerscomprising an annular plate member whose thickness substantiallycorresponds to the width of the peripheral grooves of said rollers and aplurality of mortices or grooves disposed about the periphery of saidend ring, said mortices or grooves being undercut and adapted to receivesaid rollers.

In a roller bearing, the combination of a series oi? bearing rollershaving peripheral grooves therein, a retaining ring for said rollerscomprising an annular plate member, said plate member having a pluralityof undercut mortices or grooves disposed about its periphery, saidmortices being undercut in the same direction.

3. In a roller bearing, a series of bearing rollers each having aperipheral groove therein, a retaining ring for said rollers comprisingan annular plate member whose thickness substantially corresponds to thewidth of the peripheral groove in said roller and a plurality ofmortices or grooves disposed on the periphery of said end ring, themajority of these mortices or grooves being undercut.

4. In a roller bearing, the combination of a series of bearing rollershaving peripheral grooves near their ends, an end ring for said rollerscomprising a flat annular plate memher having an unbroken innerperiphery and an outer periphery having a plurality of undercut morticesor grooves therein for the reception of said rollers and a singlestraight cut groove therein for the reception of a key roller to holdthe other rollers in such position that they cannot slip out of theundercut mortices or grooves.

5. In a roller bearing, the combination of a series of bearing rollershaving peripheral grooves near their ends, an inner and outer race, anend ring for said rollers comprising a. flat annular plate member,having an unbroken inner periphery and an outer periphery having aplurality of undercut mortices or grooves, and a single straight groovecut therein for reception of said rollers, said roller received in saidstraight groove acting as a locking means for holding said other rollcrsin said undercut mortices or grooves in position while said rollers arebeing positioned within said inner and outer race.

6. In a cage bearing, the combination of an inner and outer race member,bearing rollers, means for the reception of said bearing rollers, andmeans for locking said bearing rollers in position relative to eachother prior to their contact with said inner or outer race members andWithout changing the form or position of said receiving or said lockingmeans.

7. In a roller bearing, the combination of a series of bearing rollershaving peripheral grooves near their ends, an end ring for said rollerscomprising a flat annular plate member having a plurality of mortices orgrooves disposed about the outer periphery only, for the reception ofsaid rollers.

8. A roller bearing comprising a plurality of rollers, and supportingrings therefor, said supporting rings having roller holding socketswhich extend in a substantially radial direction and which are providedwith lateral extensions, said rings and their sockets being of such astructure that the maintenance of certain of the rollers in properposition will lock the remaining rollers against removal.

In testimony whereof I hereby affix my signature.
